The final-cut layer - a four-bar quality ladder, a named-test critique battery, campaign drift detection, and the gate every artifact passes before it ships.
Six skills that judge and direct creative work rather than make it, reviewing the output of every other Creative OS pack. Score any artifact on the four-bar quality ladder (consumer, startup, premium SaaS, keynote), run the named-test critique battery, detect drift across a multi-asset campaign, write the art-direction brief every production job starts from, resolve conflicts with the arbitration rules for when two design rules collide, and pass the pre-ship gate. Every check declares how it is verified - computed by a script, judged yes/no from an artifact, or elicited from the user - so a non-designer can trust the verdict.
